'Traditional Tibetan herb can inhibit aging'

A flowering Tibetan shrub, used in Chinese folk medicine from time immemorial, tells body cells that they are starving. This effect can become a weapon against multiple sclerosis and even aging.

The shrub Dichroa febrifugia provides a substance that may slow down aging after conversion.

The roots of the  ever-green blue hydrangea (Dichroa febrifuga) are part of the so-called Fifty Essential Herbs of Chinese traditional herbal medicine and have been used in China for centuries to treat malaria. Tracy Keller and her colleagues at the Harvard School of Dental Medicine in Boston have discovered the substance halofuginone - (in fact febrifugine, the active ingredient in the roots, but with an additional chlorine and a bromine atom) suppresses immune responses that cause immune diseases. The Latin species name, “febrifuga”, ie, an antidepressant, says it all.

Artificial amino acid deficiency
Body cells stop producing non-essential proteins when there is a shortage of amino acids. Halofuginone "simulates" such a deficiency by blocking an enzyme, T-prolyl, that transports the amino acid proline into the protein assembly, Keller's team found. The artificial amino acid deficiency triggers a chemical chain reaction, AAR (amino acid response pathway), which is a response to amino acid scarcity. AAR stunts the growth of malaria parasites and prevents the formation of a certain type of white blood cell, TH17, which is responsible for many autoimmune diseases. That in turn inhibits diseases such as multiple sclerosis, rheumatism, psoriasis and chronic inflammation of the intestines. In short: an ideal medicine for these diseases.

Against aging and warning
There is a second possible use. Animal studies show that animals that are barely fed enough live longer because diseases that cause inflammation are prevented. Keller therefore thinks halofuginone can act as an anti-aging drug.

Incidentally, be careful about using this herb on your own. Herbs, especially herbs with a powerful medicinal effect, are by definition not harmless. For example, this plant is poisonous. Inflammation is part of our body's defense system. By using this herb you weaken these defenses. In the case of TH17 cells: you protect against bacteria such as staphylococci and the Candida fungus. It is also a chemical derivative of febrifugine and not febrifugine itself. Halofuginone is now used in veterinary medicine and is an authorized “orphan drug”. Only use this and other medicines after consultation with your treating doctor, where you can provide a reference to the scientific publication. This can weigh up whether the reduced immune system outweighs the relief of complaints.

  1. Over ‘lang leven’ gesproken: “… Li Ching-Yuen or Li Ching-Yun (…; died May 6, 1933) was a Chinese herbalist, martial artist and tactical advisor. He claimed to be born in 1736, while disputed records suggest 1677. Both alleged lifespans of 197 and 256 years far exceed the longest confirmed lifespan of 122 years and 164 days of the French woman Jeanne Calment. …”


  2. Interessant artikel. Heb laatst over het effect van een dagelijks glas rode wijn gelezen, dat daarmee ook de weerstand lager wordt, waardoor reumapatienten minder last van ontstekingen krijgen. Moet je trouwens ook niet teveel van innemen, want dan krijg je het gevoel dat je reuma naar je hoofd is gestegen, de andere dag. :(
